2.2 Test procedure for test circuit 2
Figure 7. Test circuit 2 for dynamic I
H
parameter
This is a go no-go test, which can confirm the holding current (I
H
) level.
Procedure
1. Adjust the current level at the I
H
value by short circuiting the AK of the D.U.T.
2. Fire the D.U.T. with a surge current I
PP
= 10A, 10/1000µs.
3. The D.U.T. will come back off-state within 50 ms maximum.
